Playback Program (continued)
Histogram Area
The histogram is an interactive control. Not only can you get the event’s location
in time domain and its quantity of the motion percentage, but you can also select
a group of events or a period from the event histogram area and show it on the
display area.
Control Area
The control area contains almost all the control selectors and toolboxes you
need to browse the database. These control tools include location selector,
period selector, playback method selector, jog dial, display adjustment tool,
searching range adjustment tool, exporting tool, and system control tool.
Status Area
The status area is located at the bottom of the main window. It tells you the
program status information including display mode, display size, display speed,
exporting file format, and exporting file name.
Indicators
Area Selection Indicator
In the main playback window, the display area is surrounded by a blue rectangle.
This rectangle is the area selection indicator. This indicator can be set to either
display area or histogram area, as long as you move your mouse cursor to the
area you intend to select. When you select the display area, the display
adjustment tool will appear in the control area. If you select the histogram area,
the display adjustment tool will disappear and the searching range adjustment
tool will be shown in the same place of the control area.

Pull Bar
The pull bar is a fast, flexible control for seeking data in the selected time period.
It represents the total length of time in that period. You can pull the indicator on
the pull bar to the specific time-point you would like to view. The displaying
video will halt and then restart, playing the video sequence from the point you
selected. If the video sequence has been paused, the display area will show
the point you selected without playing. Note that the pull bar will only function
under the normal display mode.
Settings
After the main window is shown on the screen, you must modify the settings to
make it to work properly. Click on the “Settings” button, shown below, in the
system control tool, and the setting dialog will appear on the screen.

Database location
The most important item in the settings dialog is the database
location setting. You must set it to the directory that contains the
surveillance database to make the program to work properly.
The items in the settings windows are:
Modulation Mode:
The modulation mode cannot be changed. This depends on how
you recorded the video sequence in the monitor program. If you
select the wrong mode, the video shown in the display area will
become distorted. If you have chosen the wrong modulation
mode, you may open the settings dialog again, change to the
correct mode, and restart the playback program. The display will
now be normal.

AVI file location
This sets the
directory where exported
AVI files will be stored.
Exported AVI files will be stored in the sub-directory (camera
name) under the directory you set here.
Snapshot file location
This sets the directory where bitmap files will be stored when
you use the snapshot to export them. Exporting bitmap files will
be stored in the sub-directory (camera name) under the directory
you set here.

Normal (Single Frame) Mode
While in the normal (single frame) display mode, you can change the video
currently displayed by:
(1) Changing the database path for retrieving another one in the settings dialog
of “System Control” tool.
(2) Changing the location selector to another location in control area.
(3) Changing the playback method selector to “Full Range.”
(4) Changing the playback method selector to “Time Period.”

Histogram Area
Under the normal display (single frame) mode, you can use all the tools provided
with the playback program, except the page control. In this mode, the two labels
under the pull bar show the starting and the ending time of the interval individually
(as shown above).

Histogram Area
The histogram area in the normal display (single frame) mode only shows the
events’ occurred time and the percentage of motion detection with red bars. If
you want to access the histogram area, you must change the area selection
indicator to the histogram area. You can mark one time interval you want to see
with a color-inverted region by dragging your mouse with the left button pressed
(as shown above). When you release the left button, the color-inverted region
will be enlarged to the whole histogram area. This color-inverted region will be
the new period the program is going to display. If you change your mind and
don’t want to see that period, you can cancel it by just pressing the right button
of your mouse with the left button still pressed. If you click on the left button
without dragging it, the action will be the same as clicking on the pull bar in the
same x-axis position. That means the playback system will shift to the pointed
time and show video on the displaying frame. Besides, the dark regions in the
histogram area mean there is no existing video data in that interval. If you click
on those regions, nothing will happen except a warning message will pop up.
Using Tools
In this section, the method of how to use the tools in the control panel (shown
in the main playback window) will be discussed.
Selector Tools
The figure below shows the selector tools. They are location selector, period
selector for the selection of the beginning time and the ending time, playback
method selector, and alert area selector.
